A temporary profile is used in Halo: Combat Evolved, Halo 2, Halo 3, Halo 3: ODST, Halo: Reach, and Halo 4, when players without a profile attempt to play Multiplayer or the Campaign. When a player without a profile signs into a game, he or she will be asked if they would like the use a temporary profile.

Temporary profiles cannot be saved (and cannot earn any achievements). Temporary profiles are issued random usernames, tags, and emblems. Names include "Bozo," "Sausage," and "Caboose."


  • Rooster Teeth used the temporary profile names to create the names for some of the characters in Red vs. Blue, most notably Donut and Caboose.
  • If a profile and a temporary profile play splitscreen over Xbox Live, the temporary profile will have the same gamertag as the other profile, with a number added. If, for example, "MyGamertag" plays splitscreen with a temporary profile, the temporary profile will show up as "MyGamertag (1)."
